From an engineering standpoint, the shock placement in that pic is wrong, or at least not optimum, the swingarm has FAR too much leverage, the shock should be placed much further out on the swingarm, and about the same distance further up on the upright frame section, maintaining the 45° angle. This will allow more travel, without "stacking" the spring, or "topping out" the shock.Anything else would be too big and I believe it would cause the shocks to be too angled.
